Nantucket Maria Mitchell Association Announces Fifth Annual Green Crab Week 2024

July 31, 2024

NANTUCKET, MA - Join the Nantucket Maria Mitchell Association (MMA), Nantucket Land and Water Council (NLC), and Sustainable Nantucket (SN) for the Fifth Annual Nantucket Green Crab Week! The MMA, NLC, and SN will be offering fun daily events August 5 to August 10 to learn about, and take action against, invasive European green crabs on Nantucket.


European green crabs were first introduced to North America in the 1800s, likely traveling the ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities here on the island. Together, as a community, it is possible to help prevent green crabs from destroying the natural resources that make Nantucket’s waters so special! So please come join us during Nantucket Green Crab Week to learn more.


The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, in addition to preserving the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. For more information on the Maria Mitchell Association’s environmental work and initiatives, please visit www.mariamitchell.org.


The Nantucket Land and Water Council is a 501(c)3 environmental advocacy organization – protecting and preserving open space, harbor, pond, and groundwater, and advocating for the environment at Select Board, Planning Board, and Conservation Commission meetings. The Nantucket Land and Water Council also hosts the State of the Harbor Forum each year and Oysterfest each November to educate residents on the state of our water resources, and what we can all do to help maintain this critical resource.

Founded in 2000, Sustainable Nantucket’s mission is to preserve the community character of Nantucket while sustaining its economic and environmental vitality. Sustainable Nantucket (SN) is a grassroots, local, non-profit organization that is building a more locally-based and self-reliant food system on-island through education, advocacy, training, and partnerships which include farmers, fishermen, local food producers, schools, restaurants, and other community stakeholders.

Miss Herschel

By Jascin N. Leonardo Finger • November 10, 2025
A re-blog from years past. The item you see here is a small piece of what once was. Upon her visit to Europe as a young woman’s chaperone in 1857 –1858, Maria Mitchell visited many of the major observatories of Europe and met many of the movers and shakers in the scientific, art, and literary worlds of the continent. While Caroline Herschel (1750 – 1848) and her brother, Sir William (1738 – 1822), were long dead, Maria was able to meet Caroline’s nephew (William’s son), Sir John Herschel (1792 – 1871). All three were astronomers, though Caroline found herself having to give credit – or have her brother accept credit – for much of her work because she was a woman. She has often been credited with the being the first woman to discover a comet. She was likely not – and the other woman who was the first lost credit through history as she had to “give” her comet discovery to her husband. See a pattern? Caroline was just one of many women in a long line of, “She couldn’t possibly do that – she is a woman!” As Maria once said, “But a woman, what more could you ask to be?” But back to this small item. It was a page from one of Caroline Herschel’s notebook’s, torn from its home by John Herschel to serve a s a memento for Maria of her visit to the family’s home. Maria was a bit shocked but . . . she took it! Over the years, the paper tore and ripped and just crumbled away until Maria finally decided that to save it, she needed to past it into one of her own journals. And thus, we have what we have. I assume Caroline’s notations refer to her brother William – “Wol” and Woll.” It could be an “I” but it really looks like an “O.” She is considered the world’s first professional woman astronomer – she would be compensated for her work after some time – and she warrants a greater look at – too much for a blog. So I encourage you to go take a look at her. Maria would want you to! JNLF

From The Rear

By Jascin N. Leonardo Finger • November 3, 2025
I am not so sure our founders would love that title but the image is of the Maria Mitchell Vestal Street Observatory (MMO) “from the rear.” I love this image as it is really the only one we have – unless you count the one that is taken from farther away and from further into the backyard of the Mitchell House. That one allows you to see the natural slope of the Mitchell House back lawn which would be altered when they added the Curator’s Cottage. Both of the images were taken before the Curator’s Cottage was added at the back of the Mitchell House in the early 1930s – and this one you see here was taken before 1922 when they added the Astronomical Study onto the MMO. It also shows the original dome – which was copper – before it was replaced in 1951 – which is the current dome. The copper did not hold up to our climate here – salt spray, damp, fog. But the new one, shipped over from England, has held up well. The current dome was donated by Margaret Underwood Davis (MMA board president at the time), in memory of her son, Cushing Davis who was an amateur astronomer. Margaret Davis served as president from 1930-1946 and again from 1949-1953. The image tells you some other things too. For instance, the grape arbor behind the Mitchell House is supposed to be Peleg Mitchell’s (Maria’s uncle) grape vine – I have blogged about it several times before – and you can see it in this image. You can also see how the Milk Room connects to the 1850s kitchen. The 1850s kitchen was added by Peleg Mitchell Jr and it’s the first little wart you see with the white pipe attached. The next wart is the Milk Room – also added by Peleg – it’s the one with the shutters on the window. Both still exist it’s just the Curator’s Cottage was attached in the 1930s. You will see another chimney too. It appears alongside the white pipe. That is likely the original chimney to what is now the Astronomer’s Cottage at the MMA. We acquired the Cottage in the 1920s but I believe all of the additions, and the removal of the chimney, were done before we were given it.  Fun! JNLF
